Zusammenfassung:	An electronic device is disclosed. An electronic device comprises: a power unit for providing input voltage; a power factor correction (PFC) circuit which includes an inductor, a switch connected between the power unit and the inductor, and a bypass diode for providing the input voltage as a load, and which is connected to the load; and a control circuit for sensing the input voltage and output voltage that is provided as the load through the PFC circuit, and controlling the operations of the inductor and the bypass diode on the basis of the difference between the input voltage and the output voltage. La présente invention concerne un dispositif électronique. Un dispositif électronique comprend : une unité d'alimentation pour fournir une tension d'entrée ; un circuit de correction de facteur de puissance (PFC) qui comprend une bobine d'induction, un commutateur connecté entre l'unité d'alimentation et la bobine d'induction, et une diode de dérivation pour fournir la tension d'entrée en tant que charge, et qui est connecté à la charge ; et un circuit de commande pour détecter la tension d'entrée et une tension de sortie qui est fournie en tant que charge à travers le circuit PFC, et commander les opérations de la bobine d'induction et de la diode de dérivation sur la base de la différence entre la tension d'entrée et la tension de sortie. 전자 장치가 개시된다. 전자 장치는, 입력 전압을 제공하는 전원부, 인덕터, 전원부 및 인덕터 사이에 연결된 스위치, 및 입력 전압을 부하로 제공하는 바이패스(bypass) 다이오드(diode)를 포함하며 부하와 연결된 PFC(power factor correction) 회로 및 입력 전압 및 PFC 회로를 통해 부하로 제공되는 출력 전압을 감지하고, 입력 전압과 출력 전압의 차이에 기초하여 인덕터 및 바이패스 다이오드의 구동을 제어하는 제어 회로를 포함한다.
